Hello,
could you please tell me the meaning of the output of the polarization : Pe, Pi, Pt ?
Polarization |
+------------------------------------------------------------------------------+
| [ 4.18743352e-02 ] |
| Pe= [ -2.61147429e-02 ] |
| [ -2.25682826e-06 ] |
+------------------------------------------------------------------------------+
| [ -3.55271368e-15 ] |
| Pi= [ -3.55271368e-15 ] |
| [ 0.00000000e+00 ] |
+------------------------------------------------------------------------------+
| [ 4.18743352e-02 ] |
| Pt= [ -2.61147429e-02 ] |
| [ -2.25682826e-06 ] |
+------------------------------------------------------------------------------+
| [ -1.84660694e-02 ] |
| Pt= [ 1.84648436e-02 ] C/Meter**2 |
| [ 8.55220819e-03 ] |

Pe is the polarization contribution from the eigenfunctions in terms of fractional coordinates.
Pi is the polarization contribution from the ions in terms of fractional coordinates.
Pt is the total polarization in terms of fractional coordinates.
